DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 6 , a heat dissipation device for low-voltage complete equipment, comprising:

[0027] A main pipe 10 with closed ends is arranged under the ground and one end of which passes through the ground and extends into an external drainage channel. A drainage outlet 101 is provided on one side of the main pipe 10;

[0028] A water inlet device, comprising an L-shaped water inlet pipe 2, a stopper 3, a sealing plate 4 and a buffer device, wherein the water inlet pipe 2 is arranged in an external drainage channel and one end of the water inlet pipe 2 is connected to the main pipe 10, the sealing plate 4 is arranged on the stopper 3, the stopper 3 is slidably arranged in the water inlet pipe 2, and the buffer device is used to drive the stopper 3 to move and then return to its original position;

[0029] An air intake device, comprising a plurality of first air intake pipes 5, air outlet pipes 6 and air extraction equipment, wherein the first air intake pipes 5 are arranged on the water inlet pipe 2, and the air outlet pipes 6 are arranged on the main pipe 10 and one end of the air outlet pipes 6 is connected to the air extraction equipment;

[0030] The air supply device comprises a plurality of second air inlet pipes 7 and a box body 8 with an opening on one side, wherein the second air inlet pipes 7 are connected to the main pipe 10 and the box body 8, and the box body 8 is arranged on the low-pressure complete set of equipment;

[0031] A floating plate 9 is slidably disposed in the main pipe 10 and at the drain port 101;

[0032] The controller is electrically connected to the vacuum device to control the indirect operation of the vacuum device. In the present invention, the main pipe 10 is set underground, one end of which passes through the ground and extends to the outside drainage channel. The water inlet pipe 2 is set in another drainage channel. The box 8 is installed on the outer wall of the bottom of the low-pressure complete equipment. The air inlet hole at the bottom of the low-pressure complete equipment is in the box 8. Water flows from the water inlet pipe 2 to the main pipe 10 and then is discharged from the drain port 101. The vacuum device is controlled to work indirectly through the controller. When the vacuum device is working, the inside of the main pipe 10 is exhausted. The outside air enters from the first air inlet pipe 5 and is discharged from the air outlet pipe 6. Since the main pipe 10 is set underground and exchanges with the soil, Heat, and then the internal temperature of the main pipe 10 is low, and when water flows in the main pipe 10, the temperature in the main pipe 10 can be further reduced, and the hot air flowing into the main pipe 10 will exchange heat with the inside of the main pipe 10 and then cool down. The exhaust device does not work. When the low-pressure complete set of equipment is working, the exhaust fan on the low-pressure complete set of equipment works to exhaust the air in the low-pressure complete set of equipment. The cold air in the main pipe 10 enters the box body 8 from the second air inlet pipe 7, and then enters the low-pressure complete set of equipment from the air inlet hole at the bottom of the low-pressure complete set of equipment to dissipate heat, and can dissipate heat for multiple low-pressure complete sets of equipment at the same time. Specifically, the exhaust device is an exhaust pump. When the length of the main pipe 10 is long, the exhaust fan on the low-pressure complete set of equipment cannot draw external air into the main pipe 10, and then flow into the low-pressure complete set of equipment through the second air inlet pipe 7. By setting the exhaust device, external air can flow into the main pipe 10; the controller is set indoors.

[0033] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0034] In this embodiment, a plurality of support plates 201 are provided at the bottom of the water inlet pipe 2 to support the water inlet pipe 2 so that the water inlet of the water inlet pipe 2 is higher than the bottom of the drainage channel, thereby reducing the entry of sand and gravel into the main pipe 10.

[0035] In this embodiment, a discharge port 202 is provided at the bottom of the water inlet pipe 2; the buffer device includes a vertical plate 11, a spring 12 and a T-shaped first sliding rod 13, the vertical plate 11 is arranged in the water inlet pipe 2, the first sliding rod 13 can slide on the vertical plate 11 and one end of the first sliding rod 13 is connected to the stopper 3, the spring 12 is sleeved on the first sliding rod 13, a grid hole is provided on one side of the first sliding rod 13 and the bottom of the first sliding rod 13 blocks the discharge port 202, and a grid hole is provided on one side of the first sliding rod 13, which can convect the water in the main pipe 10 Filter, intercept some floating objects and some large particles. When the water level rises, the sealing plate 4 is pushed by the water and moves to the right, driving the block 3 to move to the right, causing the first sliding rod 13 to move to the right, the spring 12 is squeezed, the discharge port 202 is opened, and the floating objects are discharged from the discharge port 202. At the same time, the water inlet end of the water inlet pipe 2 is blocked by the sealing plate 4 to prevent a large amount of floating flow from accumulating in the water inlet pipe 2 when the water level rises, causing blockage, and subsequent inconvenience from being discharged from the discharge port 202. When the water level drops, the force on the sealing plate 4 becomes smaller, and the spring 12 gives the block 3 a reaction force to return it to its original position. The size of the discharge port 202 and the width of one side of the first sliding rod 13 can be set according to actual conditions.

[0036] In this embodiment, a transverse plate 102 is provided in the main pipe 10, and a second sliding rod 901 is provided on the floating plate 9. The second sliding rod 901 can slide on the transverse plate 102, and the floating plate 9 floats on the water level in the main pipe 10. During drought, the water level in the drainage channel drops, and the water entering the main pipe 10 becomes less. The floating plate 9 moves downward through the second sliding rod 901, so that the opening of the drain port 101 becomes smaller. When the air extraction device is working, the water outlet of the main pipe 10 is relatively sealed, and air will still flow in from the first air inlet pipe 5, achieving the effect of heat exchange and cooling inside the main pipe 10. Specifically, one side of the floating plate 9 contacts the inner wall of one end of the main pipe 10.

[0037] In this embodiment, a cooling device is also included, which is arranged in the main pipe 10 to cool the inner wall thereof.

[0038] In this embodiment, the cooling device includes a rotating rod 14, a fixing plate 15, a sponge plate 16 and a plurality of blades 17. The fixing plate 15 is arranged in the main pipe 10. The rotating rod 14 is rotatably arranged between the wall of the main pipe 10 and the fixing plate 15. The sponge plate 16 and the plurality of blades 17 are arranged on the rotating rod 14 respectively. The sponge plate 16 is provided with a sponge. Water flows from the water inlet pipe 2 into the main pipe 10 and falls on the blades 17 to drive the rotating rod 14 to rotate, thereby driving the sponge plate 16 to rotate. At the same time, the air that quickly flows into the main pipe 10 will also drive the blades 17 to rotate. After the sponge plate 16 is wetted with water, it contacts the inner wall of the upper part of the main pipe 10 to cool it down. When the external air flows into the main pipe 10, it can cool the external air more quickly. Specifically, bearings are arranged on the inner wall of the main pipe 10 and the fixing plate 15. Both ends of the rotating rod 14 are arranged in the bearings to reduce the friction of rotation.

[0039] In this embodiment, the bottom end of the main pipe 10 is an inclined surface, which facilitates the discharge of sludge in the main pipe 10 .
